Negotiators Notepad 19-08 discusses this some. Here is an excerpt from an email dated 1/9/2020 from DalComm...Update on Completed Sections

In addition to the specifics provided in Part 1 of the update, ALPA and Delta have reached conceptual agreement on several sections, but are still working on final PWA language. Once the language is finalized, these sections will then be declared TAs:

• Section 4 – Minimum Pay and Credit Guarantees
  Gains providing pay for required Chief Pilot visits, pay above guarantee for short-call assignments, and improvements for reserve pilots who have a green-slip/inverse assignment cancelled.
• Section 14 – Sick Leave
  Improvements have been secured on automating how a pilot calls in sick and well. Verification triggers have been improved by eliminating the 160-hour threshold. Limitations on the Company's usage of Good Faith Basis have been established, and exclusions for acute conditions and non "major bones" have been eliminated.
• Section 16 – Crew Augmentation and International Operations
  Established a requirement for rest facilities on all new aircraft conducting augmented operations: Class I for widebody, and Class II for narrow body. Usage of A330 aircraft with one bunk on flights over 12 hours will be phased out.
• Section 24 – General
  Jumpseat improvements, and a paid commuter parking benefit have been secured.
